Staged surgical intervention to treat dysphagia caused by Kommerell's diverticulum.

Kommerell's diverticulum is a rare congenital vascular anomaly. Dysphagia is one indication for surgical intervention. We report on 4 consecutive patients who presented with dysphagia caused by Kommerell's diverticulum and underwent staged surgical treatment. The key to surgical treatment for such patients is to remove the vascular structure completely from the vicinity of the oesophagus.
